Controller
The E5EK DRT supports following inputs: temperature input, current
input, voltage input, CT input and remote SP input.
Only one of temperature input, voltage input and current input can be
selected and connected to the controller. The above figure shows temper
ature input connected to the controller.
The following input sensors can be connected for temperature input:
Thermocouple: K, J, T, E, L, U, N, R, S, B, W, PLII
Platinum resistance thermometer: JPt100, Pt100
The following currents can be connected for current input:
4 to 20 mA, 0 to 20 mA
The following voltages can be connected for voltage input:
1 to 5 VDC, 0 to 5 VDC, 0 to 10 VDC
Connect CT input when using the HBA (heater burnout alarm) func
tion. Note that the HBA function cannot be used simultaneously with
the linear output unit.
When the remote SP function is enabled, inputs within the range 4 to 20
mA are used as the remote SP .
